Saitama is one of the strongest human being in existence out of all anime, but what can beat him in the OPM world? Here are 3 characters that can beat Saitama in OPM.
1. Mumen Rider
Mumen Rider is the top C-Class hero in OPM. He doesn’t do much damage to Tiger level threats too, but he has decent stamina. So, how can he beat Saitama? Well, in this webcomic by Faker, Mumen Rider has a secret killer move that can finish God level threats with his mind. But, Saitama has to beat it in a punch. In chapter 958 of the webcomic, Mumen Rider used his golden bicycle and wiped out the entire universe. In conclusion, Mumen Rider is one of the strongest human being in the whole anime series.
King is a Class S Rank 7 Hero of the OPM series. For people who haven’t seen Season 2 of OPM, the next part will be spoilers. In Season 2 of OPM, King was exposed and he was actually a normal human being, just like any other humans. But, he even survived a Demon level threat, even as a normal human. So, how is king stronger than Saitama? Well, in chapter 959 of the webcomic by Faker, Mumen Rider gave king all of his power by cutting himself and making King drink his blood. So, king somehow turns more powerful then Mumen Rider and turned evil. In conclusion, King is one of the strongest beings in the OPM series.
Mosquito is a Mosquito, created by Mosquito Queen in Season 1, Episode 2 of the OPM series. Mosquito was not killed by Saitamas slaps and he was not hurt in any way. After Mosquito Queen got defeated by Saitama, Mosquito got really furious and he went into a barrier that will get him to sleep for 10 years and get out more powerful. 10 years later, he somehow defeated King by sucking his penis blood and King commuted suicide. So, he got more powerful than king and he is stronger than Zeno from DBZ. He can wipe out existence with snapping his finger or using his mind. In conclusion, Mosquito is the strongest anime character in the whole anime world.
Note: This is all true and I would never lie about OPM.
Spoiler: Saitama drank his blood after that and he turned more powerful than anyone.
